pretty sure it's polished and buff to get that shinny. cast aluminum wouldn't come out like that. i think there might be some kind of chemical polishing on aluminum. I know you can do...

Thanks! Problem solved. After looking around, we found the backup of the SRAM file in our PC.

Restored the SRAM and the problem is gone. Keeping our finger cross hoping the problem won't come back.

we got a new machine with BT30 spindle and all new BT30 holders.

the holders are sticking to the spindle taper. wiping some wd-40 on the taper helps, but problem seems to come back after the wd-40...

(see attached pic) This error comes up on my Lathe with 21i-T. When this error comes up, the panel stays until power down and on again.

material? thru hole or blind hole? how deep?

I use the G53 method also. "G0 G53 X16. Y0"

My mill has the umbrella type toolchanger. With the usual "G0 G28 Z0" at the end of each tool, it has to come back down like 4 inches for tool change....

i have a takisawa with live tooling also. This is something my camworks post puts out, with a little bit of hand edit on the starting rapid position.

Attach your file and I'll see if I can give you some advise.

Guess I didn't explain it clearly enough. My point was that if you had to round off even the the 4th digit after the decimal point, you can end up with a circle that's almost .010".

So lets say...

I don't know the math behind it. But it's very easy to see why R method and 180deg arc is bad with this example.

draw an arc in your cad program with the
start of the arc at x1.0 y0
end of the...

It's has always puzzled me how tool manufacturers make the thru holes in endmill and carbide drills. Anyone know?

Yes, I've tried google it and didn't find any info on it.

I had ran into a similar problem on my mill. I solved it by changing the cam system to post circle at max of 90deg sweep instead of 180deg.
can you post your code? hard to explain in word, but let...

try adding a G1 xy move before G3. i think it doesn't like the Z movement before the G3. even if the xy move doesn't actually move at all. like this:

with M03 and M29Sxxx in the code, the spindle would stop and start again at the R point. that's why I thought it might have rigid tapping. But they seem to do the same thing with or without M29. I...

No, the spindle doesn't start without a M03. It would just sit there waiting forever (no alarm).

I am working on a Atrump Mill with OM-D control.

When rigid tapping (M29S300, G84.......), at the bottom of the stroke, the Z axis does not synchonize with the decel/reverse/accel of the spindle....

Just start a new post in UPG, use Fanuc as the template. It should get you close enough. UPG is very easy to learn. Try it out, post question and we'll try to help you out.

have you tried using z-level instead of pattern project?

even in pattern project, you can reverse the stepover, that might work for you also.

one advise I would have is to go to your local metal supplier/distributor, see what they sell. most of the time when I design stuff, what's available...

few years ago at my previous work place, we went from mastercam 9 to camworks 2006/2007. It was great. I hated drawing in mastercam, especially when compared to solidworks. not having to deal with...

Your reasoning might have sounded good, but the logic behind it doesn't make sense. If you're looking at the opportunity cost of 15min of a day, that can only means the shop is running 24hr a day....

I've used a 3016L with the 88 controller before.
It didn't need the D number for cutter comp.

Sounds like the post processing file needs some modification.

bump.

Anyone used it yet?

When I am setting the tool height, under the offset/Geom page, I press both "EOB"+"Z" at the same time to enter the current relative "Z" number into the tool height offset.

This works fine as long...

Has anyone used one of these cheaper digital protractor (inclinometer).

Thank you Geof. That worked perfect!

I got a question about G28, homing the Z axis on a Fanuc OM-D.

currently, all my program at the end of each tool, there is a line:
G91 G28 Z0.

and it homes the Z axis to the machine zero....

Ah! I totally forgot about that part of Vericut.

There is also Surfcam with their Velocity or whatever it's call.
